Example 1: Measurement of Illuminance of Ultraviolet Ray Resulting in a Given Strain
[0445]Illuminance of an ultraviolet ray for producing a polymer with a given strain is determined by the following procedure.
[0446][Derivation of Relationship Between Strain-Illuminance]
[0447]1) Provision of Starting Material Monomer
Example
[0448]A suitable monomer is selected for each specific example for Example 2 and Examples thereafter. For example, for the (meth)acrylic polymer in Example 2, a monomer component comprising a polymerization initiator is provided by mixing 7.03 g of ethyl acrylate, 0.17 g of diethylene glycol dimethacrylate, and 0.0042 g of 2,4,6-trimethylbenzoyl diphenylphosphine oxide [BASF, product name: Irgacure TPO] as the polymerization initiator.
[0449]2) Irradiation of Ultraviolet Ray with Specific Illuminance onto the Starting Material Monomer for Polymerization
[0450]Once an appropriate monomer component is obtained for each Example, an ultraviolet ray is irradiated thereon. For example, for Example 2, the obtained monomer component is injected into a transparent glass mold with a release film (vertical: 100 mm, horizontal: 100 mm, depth: 0.3 mm), and then an ultraviolet ray is irradiated on the monomer component so that the amount of irradiated rays is 0.5 to 50 mW / cm2 to subject the monomer...

Example 3
[0466]Acryl Resin (2)
[0467]A monomer component comprising a polymerization initiator was obtained by mixing 30.01 g of ethyl acrylate, 0.35 g of 2-hydroxyethyl acrylate, and 0.038 g of 2,4,6-trimethylbenzoyl diphenylphosphine oxide [BASF, product name: Irgacure TPO] as the polymerization initiator.
[0468]A (meth)acrylic elastomer was obtained by injecting the resulting monomer component into a transparent glass mold with a release film (vertical: 100 mm, horizontal: 100 mm, depth: 2 mm), and then irradiating an ultraviolet ray on the monomer component so that the amount of irradiated rays was 0.5 to 50 mW / cm2 to subject the monomer component to bulk polymerization. The following Table 2 shows the measurement results.
